Banana is a climacteric fruit that produces enough ethylene to change its physicochemical
characteristics such as colour, texture, aroma, chemical composition,
respiration rate and senescence. Ethylene, a colourless gas, is the main regulator of
ripening in climacteric fruits which leads to the short marketable life and increase
postharvest losses. These losses can be reduced by adopting non-commercial charcoal
from agricultural wastes that capable to absorb ethylene gas from banana such as
palm kernel shell (PKS) at varying sizes (0.5 mm, 1.5 mm and 0.3 mm PKS charcoal).
No apparent effect of various sizes of PKS charcoal on ethylene production and also
other postharvest quality parameters were observed. Moreover, irrespective of sizes,
PKS charcoal had the ability to prolong the shelf life of banana by maintaining the skin
greenness and reducing SPI score In conclusion, PKS charcoal without regard to sizes
can delay ripening and maintain postharvest quality of berangan banana.
